WASHINGTON — President Donald Trump initially responded on Twitter to British Prime Minister Theresa May’s criticism of his retweeting of inflammatory anti-Muslim videos from a fringe British political group by directing his message to the wrong Theresa May.

Online archives of Trump’s tweets show the president tweeted Wednesday night to a Twitter user with the handle @theresamay. That user is identified as a woman with a different last name who only has six followers.

That tweet was soon deleted and Trump sent a new message to May’s correct Twitter handle, @theresa–may. He told May not to focus on him and instead worry about “destructive Radical Islamic Terrorism that is taking place within the United Kingdom.”

.@Theresa_May, don’t focus on me, focus on the destructive Radical Islamic Terrorism that is taking place within the United Kingdom. We are doing just fine!

On Wednesday Trump re-tweeted three videos posted by Britain First, purporting to show violence from Muslims. The U.K.-based group, which grew out of anti-immigrant movements including the all-white British National Party, opposes “the colonization of our homeland through immigration.”

Ever since Theresa May extended an invitation to Trump to come visit the Queen, he has rankled the nation with his off-the-cuff comments about terror attacks in Britain.

“I have previously called on Theresa May to cancel her ill-judged offer of a state visit to President Trump,” London Mayor Sadiq Khan said in a statement released by office. “After this latest incident, it is increasingly clear that any official visit at all from President Trump to Britain would not be welcomed.”

As far back as January, an online petition calling for Trump to be prevented from making an official state visit had shot past 1 million signatures. The topic is a tricky one for May — who needs to maintain the veneer of a “special relationship” with a historic ally whose leader is unpredictable and has put her in awkward diplomatic situations. She also needs to find new trading partners as the U.K. heads towards leaving the European Union.

Trump and Khan have history. It began after the terror attacks on London Bridge when the president criticized Khan’s response: “Pathetic excuse by London Mayor Sadiq Khan who had to think fast on his ‘no reason to be alarmed’ statement,” the president tweeted.

In London, May’s spokesman James Slack told reporters: “where Islamist extremism does exist, it should be tackled head on. We’re working hard to do that, both at home and internationally, including with our US partners.” Slack repeated that Trump had been “wrong” to promote the videos.

Trump’s support of Britain First and his direct criticism of May via Twitter have enraged U.K lawmakers. In Parliament in London Thursday lawmakers united to condemn him, calling on Home Secretary Amber Rudd to cancel the proposed state visit and urging the U.S. president to delete his Twitter account. Rudd was speaking as May traveled in the Middle East.

Labour’s Stephen Doughty on Trump: “by sharing it he is either a racist, incompetent or unthinking or all three.” Conservative lawmaker Tim Loughton said Twitter should take down the account of “the first citizen of the United States.”

Luciana Berger, a Labour lawmaker who has suffered anti-semitic abuse on Twitter, said “Donald Trump is now actively sowing seeds of hatred in our country” and her colleague Paul Flynn said “if he comes to this country, Trump should be treated like anyone else who breaks the law and “charged with inciting racial hatred.”

Rudd said that while “many shared” the view that Trump should delete his Twitter account, she was careful to distinguish between the holder of the office and Britain’s relationship with its historical ally, the U.S.

She repeated the government’s insistence that the invitation to Trump had been extended and accepted: “We must remember that the United States itself has such an important relationship with this country in terms of keeping us safe as well.”

She is also called on social media companies such as Twitter to do more to tackle extremism and hate-speech online.
